YZS Four-Girder Casting Overhead Crane

For steel plants requiring a four-girder, four/six-rail, double-trolley casting crane for molten-metal transfer, ladle tilting and auxiliary lifting.

The YZS four-girder casting crane is a heavy metallurgical bridge crane for molten-metal transfer, pouring and tilting operations. The source specifies a four-girder, four- or six-rail, double-trolley layout.

The main trolley uses a double lifting-point fixed gantry plate-hook device for the molten-metal ladle, while the auxiliary trolley uses a forged hook and runs on separate rails. Buyers should define ladle reactions, tilting sequence, auxiliary lifting duties and production cycles.

Product Overview

Four-girder, four- or six-rail, double-trolley metallurgical crane.

Main trolley uses a double-lifting-point fixed gantry plate-hook lifting device.

Auxiliary trolley uses a forged hook and runs on separate rails.

Any capacity, span, speed, temperature limit, synchronization accuracy or other guaranteed performance value that is not published on the source page should be confirmed from the actual project and written into the technical agreement.

Application Scenarios

How to Select the Right YZS Four-Girder Casting Crane

1. Define Main-Trolley Load

Include ladle, molten metal and gantry lifting device.

2. Define Auxiliary-Trolley Load

Provide independent auxiliary hook duty.

3. Define Tilting Sequence

State the geometry and required relative trolley/hook movement.

4. Define Rail / Building Loads

Four/six rails create project-specific runway reactions.

5. Define Safety / Monitoring

Specify required limits, safety monitoring and acceptance tests.

Safety & Control: What Buyers Should Confirm

Installation & Maintenance

Before manufacture and installation, confirm runway span, rail / runway-beam condition, elevation, available headroom, process equipment clearances, heat sources, electrical supply and erection access. The metallurgical lifting device and safety interfaces should be frozen before production.

Maintenance should follow the final supplied manual and plant safety procedures. In addition to normal crane mechanisms, metallurgical cranes require attention to heat shields, high-temperature cables, brakes, safety limits, lifting devices and safety-monitoring functions.

What Information Do We Need for a Quote?

Frequently Asked Questions

How is crane capacity selected?

Use the complete suspended load, including the ladle, box, clamp, lifting device or other below-the-hook equipment.

Can capacity and span be customized?

Yes. Unless the source page states a fixed range, capacity and span should be engineered from the project.

Why is radiant heat data required?

Metallurgical crane structural, cable, motor and protection design depends on actual thermal exposure.

Can automation be added?

Where the source confirms PLC, VFD or automation capability, the final automation scope should be defined by the buyer's process and acceptance requirements.

What should be written into the technical agreement?

Any performance that matters contractually—duty, speed, heat protection, synchronization, weighing, automation or safety function—should be stated with its acceptance method.
